EXECUTIVE SUMMARY
Not applicable.

RECOMMENDATION
That Council note the report by the Project Coordinator – Flooding, Coastal and Foreshore to the
Services & Organisation Committee Meeting dated 12 March 2019 providing an update on the
development of a Shoreline Erosion Management Plan (SEMP) and also note the formation of a
staff Noosa Spit SEMP Project Working Group to oversee that project.


REPORT
1.                       Background
In November 2018, Council approved the completion of a Shoreline Erosion Management Plan
for Noosa Spit to address priority erosion issues and recommend preferred management options.
That resolution also requested that quarterly status updates be provided to Council.
2.                       Shoreline Erosion Management Plan
In line with Council’s procurement guidelines, an Invitation to Quote (ITQ) was delivered to three
consultants for the development of a Shoreline Erosion Management Plan (SEMP) for Noosa
Spit. This ITQ process closed on 4 February 2019, with three submissions received. The ITQ
was recently awarded to BMT WBM Pty Ltd for $121,325.00.

The project will develop a sound technical foundation for the dynamics of the lower Noosa River
and review historical causes for erosion including an exploration of historical and environmental
factors that have led to the existing eroded condition. Building on this technical foundation, the
consultants will then use computer-simulated models to explore changes to the river alignment
and evaluate possible solutions to mitigate erosion risk to Noosa Spit, without causing negative
impacts to neighbouring sites.

This work will then be combined to produce a SEMP, which will set out a management strategy
for Noosa Spit based on an erosion “trigger line” approach that has proven successful at other
sites. The development of the SEMP will seek input from state regulatory bodies, as well as
Council-facilitated stakeholder consultation, to ensure that the proposed strategy has the best
opportunity for streamlined implementation.

The SEMP is expected to be delivered by November 2019, with the project phases and
anticipated milestones provided below:
